I'm using latest Samba on my scholl PDC server with 64bit RHEL4. I'm using utmp logging (utmp=yes). Since 3.0.23c I have a problem with outstanding logged-in counter (output of command w or command top). In the time before it was possible to clean the counter by restarting Samba. This not possible since 3.0.23c (AFAIK).
The problem is not shown on the second server with the same Samba build for but for x86 arch. There is my repository:
